Overview

Description from the maker (original English)

Local Mac API-key vault: Touch ID-approved, scoped grants for agents, not keys. Needs Keysrs.app.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Download the maker’s .mcpb file

The link goes to the maker’s own file; we do not host or repackage it. Open the file and Claude Desktop installs it.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is Keysrs safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.16.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.

What can I use instead?

Keysrs

Short-lived tokens for AI agents, on your Mac and on cloud VMs. Your real API keys stay in the macOS Keychain; agents get a scoped token instead.

  • MCP-first. Agents talk to Keysrs over MCP: they find keys in a project, import them, and ask you for access. You approve each grant with Touch ID.
  • Short-lived tokens. A grant covers one key, one host and minutes to hours; a project token lasts 30 days. Revoke everything in one call.
  • Cloud VMs too. A VM or sandbox gets a token, never the key. Its calls come back to the gateway on your Mac, over SSH or a relay you deploy yourself, and the real key is swapped in there.

Keysrs also charts the calls made through its gateway: tokens, requests and estimated spend per key and provider.

Free and MIT-licensed. macOS 14+ on Apple Silicon.

Install

Download Keysrs-arm64.dmg from keysrs.com or the latest release, drag Keysrs to Applications and open it. It runs in the background (no Dock icon or window until you open it again) and updates itself.

For the keys command line, choose Install Command Line Tool… in the Keysrs menu, which links ~/.local/bin/keys.

Use it with your agents

keys setup mcp

This registers the Keysrs MCP server with Claude Code, Codex, Cursor, Droid and Claude Desktop. Restart the agent, then ask it in plain words:

  • "Scan this project for API keys with Keysrs." It finds credential-shaped variables in your env files and reports names and last-4 hints, never values.
  • "Import and wrap this project's keys." One Touch ID moves the keys into the macOS Keychain and rewrites the env files to a 30-day project token.
  • "Ask me for a Keysrs grant for the key anthropic, 30 minutes." You approve with Touch ID; the agent gets a token scoped to one key, one host and a time limit.
  • "Revoke everything." Ends every grant, project token and relay pairing at once, and turns the relay off.

keys unwrap puts the original values back.

Cloud VMs

keys gateway on openai                               # once per key

keys client issue openai --label "my vm" --days 7 # a revocable token for the VM keys tunnel user@my-vm # VM reaches the gateway over SSH

On the VM, point the agent at http://127.0.0.1:12767/openai and use the ksfc_… token as its API key. For a sandbox you can't SSH into, keys relay carries the same gateway through a Cloudflare Worker you deploy into your own account, and keys share "my box" --key openai hands a machine several keys at once through it (one token, one pairing, printed as env lines to paste). See cloud agents and the relay.

From the command line

keys add                                  # guided: provider, name, hidden secret

keys list keys grant openai --minutes 30 # a scoped token for a script keys env openai OPENAI_API_KEY -- python run.py keys spend --week keys help # every command

Details: the full guide, agents and MCP, cloud agents and the relay.

Privacy

  • Everything listens on 127.0.0.1 only. The one optional way in from outside is a relay Worker you deploy into your own Cloudflare account, and keys never travel over it.
  • No tool, log, screen or report ever shows a key value. Copy, reveal, env and rotate ask for Touch ID every time.
  • Keysrs counts only the calls made through its own gateway; it reads no other tool's logs. It never reads ~/.codex/auth.json, ~/.grok/auth.json, browser cookies or provider websites.
  • The app sends no analytics or telemetry.
  • Update checks are one cookieless request to GitHub's release API.

Build from source

make build                     # signed debug CLI at .build/debug/keys

python3 scripts/build-app.py # Keysrs.app from the release build swift test # offline; CI's env is in test.yml

Signing setup is in SIGNING.md; .github/workflows/test.yml is the full list of checks CI runs.

Keysrs was called Keysreallysafe; the repository, the Keychain service and the data folder keep that name so existing installs keep working.
